I don't have an issue with him buying to make money, it's just the way he goes about it. I find him rude to be honest. If he just PM'D people instead of posting his offers in a public forum it would be better.
He kept sending me offers for things on ebay aswell, I told him that i will not take less than £750 on something as iv'e been offered that and he replies offering like £500? That's just plain retardation.
I then listed a van for sale at £3750 and he sent me several offers at £37?? , It seems to me that he's a timewaster, He asks loads of questions and says he will have it but when it comes down to it he buys very little.
